Reclaiming Polluted Marine Sediments. A Case History
The Development Plan of Taranto port (S. Italy) predicts the dredging of approx.20 Mt sediments, ≥10% of which are polluted. By appointment of Italian Environment Ministry, a detailed experimental investigation was carried out at laboratory and pilot-scale levels on the best available techniques to reclaim the polluted sediment so to reuse it in a technic and cost effective manner. A short pre-...
متن کاملBioremediation of oil polluted marine sediments: A bio-engineering treatment.
The fate of hydrocarbon pollutants and the development of oil-degrading indigenous marine bacteria in contaminated sediments are strongly influenced by abiotic factors such as temperature, low oxygen levels, and nutrient availability. In this work, the effects of different biodegradation processes (bioremediation) on oil-polluted anoxic sediments were analyzed. In particular, as a potential bio...
متن کاملIsolation of anthracene resistant positive gram bacteria from Imam Khomeini Port oil polluted sediments
Today's most of microorganisms are used for purification of hazard waste such as municipal and industrial waste water and oil contaminants. In this study 2 bacterial species were isolated and purified in hydrocarbon (anthracene) containing media from oil polluted sediment of Imam Khomeini port. Bacillus pasteurii and Amphibacillus xylanus species were identified as indicator degrading bacteria ...
متن کاملBottom Sediments of Lake Nicaragua and Lake Managua, Western Nicaragua
Lakes Nicaragua and Managua are large, rather shallow, fresh-water bodies that lie in a late Tertiary and Quaternary graben in western Nicaragua. The bottom sediments comprise highly organic diatomaceous volcanic silts and clays in which quartz plagioclase feldspar, dioctahedral montmorillonite and volcanic glass are the principal constituents. ' Organic nitrogen content of the lake sediments r...
متن کاملLeaching of heavy metals from dredged bottom sediments
Deposition of sediments on land in atmospheric conditions causes many risks connected with environmental protection. Particularly dangerous is leaching of heavy metals from sediments deposited on land The research aimed at assessment of leaching of heavy metals from dredged bottom sediments potentially disposed on land. In this research it has been shown that the leaching of heavy metals during...
